"We ratify the ruling of February 14 2011 in all its parts, including the sentence for moral reparation," stated the court in the city of Lago Agrio in its ruling, as cited by Reuters.
The California-based energy company appealed against the February ruling on the grounds that that it was not responsible for chemical-laden wastewater dumped in jungle land from 1964 to 1992 by Texaco, which Chevron acquired in 2001.
In an email statement obtained by Bloomberg after the hearing, the energy giant lambasted the Ecuadorian appeals court’s decision, describing it as “another glaring example of the politicization and corruption of Ecuador’s judiciary that has plagued this fraudulent case from the start.”
By the time of last year's judgment, the case had been making its way through US and Ecuadorean courtrooms for more than 17 years.
The suit was originally filed in a New York federal court in 1993 against Texaco, but was dismissed three years later after the oil company argued at the time that Ecuador was the proper venue to hear the case.
According to Chevron, Texaco had spent more than $40 million cleaning up the area during the 1990s, and had also previously signed an agreement with Ecuador in 1998 absolving it of any further responsibility.
But the 30,000 Ecuadorians, who were represented in the lawsuit, chose to pursue the case for environmental contamination and illnesses that had allegedly resulted from Texaco's operation of an oil consortium in the Amazon.
